Mare Crisium is that interesting isolated sea on the northeastern side of the visible lunar surface. Not long before beginning the sketch, it became fully illuminated.
The Nectarian Period impact event that formed this feature occurred more than 3.8 billion years ago. The mare portion of the basin is about 500 kilometers across. In the grazing sunlight on the floor, wrinkled ridges were visible. Also on the western floor craters Picard (24 km.), Peirce (19 km.) and Swift (11km.) stood out in the low light. I could see the lighter gray bench lava that partly buried craters here such as Yerkes (37 km.). Tall flat top mountains (massifs) beyond the shore stand at 2-5 kilometers above the sea. Both promontoria Lavinium and Olivium stood out clearly in very brief moments.
Sketching:
For this sketch I used: 400 series black Strathmore Artagain paper 9″x 9″, white and black Conte’
pastel pencils , and Conte’crayons, a blending stump, plastic eraser.
Telescope: 13.1 inch f/ 6 Dobsonian with 6mm (332x)
Date: 2-13 & 14-2013 23:00 – 00:45 UT
Temperature: 1.7°C (35°F)
Weather: clear, calm
Seeing: not good Antoniadi IV
Co longitude: 310.9°
Lunation: 3.69 days
Illumination: 15.7%

Jef, Michel, Tom and Jim,
Thank you all for your kind comments. A fun sketch but I was not comfortable with the rush. Amazing to have a partly clear night in winter.
Best to all of you in your sketching/observing.

Such masterful control of the media, Frank, despite the 'rush'. How often have we seen a 'rushed' job just excell because it isn't overworked. Lovely stuff.
Alex.

Alex, Mike and Peter,
Thank you for all the nice words.
--
Alex - You certainly are correct about the over doing it while sketching, I have ruined my share by over working some.
--
Mike, and Peter - Don't think for one minute that you can't do this lunar sketching or any kind of sketching. What helps more than anything is free time to practice.

Frank,
Let me repeat--Wow! This is one of your best. I like the second sketch with labels, too.
Thanks for encouraging the rest of us to sketch Luna, even if she is kinda scary.

It is not easy to sketc Crisium, because it is so large: The brightness difference is huge! I am glad to see this fine sketch, thank you.

Pete and Uwe,
Thank you both for your kind words.
I was hoping to get the entire basin to the rim but not this time.

Yes, but the tonal subtleties and differences on the part of the basin floor that you could see are extremely well rendered.

I like to go after the waxing crescent Moon features from now until June and the waning crescent in Fall. Spring can be tough viewing for seeing but now and then I get lucky.

Great sketch Frank,Is that Yerkes the corrupt Chicago transportation tycoon that got a crater on the moon named after him just because he financed an observatory? Maybe we should offer the same deal to Gates or some other uber rich person, imagine the boom in observatories being bulit. lol.

Tommy5,
Mr. Yerkes A.K.A. Chicago's very own Mr. Larceny. For his behavior, life in prison would have been too good. You know your Chicago history T5.
Thanks for the kudos.
